Ancient DNA analysis of elite nomadic warrior from Chinge-Tey I funerary commemorative complex in the "Valley of the Kings", Tuva.

Background: In the I millennium BC bearers of the Scythian-type nomadic cultures inhabited the steppes of Eurasia, from Northern China to the Carpathians. According to archaeological data, the origin of nomadic life style and economy can be traced to the eastern part of this steppe "corridor", primarily to the territory of the present-day Republic of Tuva in Russia. Here, in the Turan-Uyuk Basin, also known as the "Valley of the Kings", some of the earliest known Scythian-type archaeological sites called Arzhan-1, Arzhan-2, Chinge-Tey I, Tunnug 1 were studied.

Aging women in Russia: Between sexless and sexy oldies.

Women's sexuality as a dimension of embodied identity is shaped and constrained by social norms of gender and age and negotiated by women in complex ways. Discourses of hegemonic bodily normativity ascribe a sexless subjectivity to Russian women in their post-reproductive years, contributing to their social exclusion. At the same time, in modern Russian society a neoliberal concept of "successful active aging" is gradually changing understandings of aging, making later-life sexuality more visible and legitimate.

[The scientific triumph and philosophical dilemma of V.M. Bekhterev].

An important area of V.M. Bekhterev's scientific research, which to this day does not have a productive resolution and remains controversial, was an attempt to combine the science of the human psyche with a speculative philosophy close to pantheistic views about the «universal soul».

Lessons from COVID-19 for behavioural and communication interventions to enhance vaccine uptake.

The Covid pandemic has yielded new insights into psychological vaccine acceptance factors. This knowledge serves as a basis for behavioral and communication interventions that can increase vaccination readiness for other diseases.

Impact of cross-reactivity and herd immunity on SARS-CoV-2 pandemic severity.

Public health systems reported low mortality from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in East Asia, in low-income countries, and for children during the first year of the SARS-CoV-2 pandemic. These reports led commentators to suggest that cross-reactive immunity from prior exposure to other pathogens reduced fatality risk. Resolution of initial infection waves also contributed to speculation that herd immunity prevented further waves prior to vaccination.

Atrial fibrillation: real-life experience of a rhythm control with electrical cardioversion in a community hospital.

Background: Atrial fibrillation is the most prevalent sustained cardiac arrhythmia. Electrical cardioversion, a well-established part of the rhythm control strategy, is probably underused in community settings. Here, we describe its use, safety, and effectiveness in a cohort of patients with atrial fibrillation treated in rural settings.

Biological Reductionism as an Obstacle to the Advancement of the Biopsychosocial Concept of Mental Disorders.

The substantial progress in neurobiological technologies has narrowed the horizons of many psychiatrists, ultimately leading them to focus exclusively on biomedical research, primarily aimed at studying the biological basis of mental illnesses. This has led to an unjustified dominance of the biomedical paradigm in understanding the nature of mental disorders, while virtually ignoring the study of other components of the disease related to the psychosocial maladjustment of patients. This trend, largely associated with advancements in neuroscience employing neuroimaging techniques to study the brain's activity as a biophysical object, has contributed to the development of such innovative field as evidence-based medicine.

Ambiguity in Ethical Standards: Global Versus Local Science in Explaining Academic Plagiarism.

The past decade has seen extensive research carried out on the systematic causes of research misconduct. Simultaneously, less attention has been paid to the variation in academic misconduct between research fields, as most empirical studies focus on one particular discipline. We propose that academic discipline is one of several systematic factors that might contribute to academic misbehavior.

International burden of cancer deaths and years of life lost from cancer attributable to four major risk factors: a population-based study in Brazil, Russia, India, China, South Africa, the United Kingdom, and United States.

Background: We provide a comprehensive view of the impact of alcohol consumption, tobacco smoking, excess body weight, and human papillomavirus (HPV) infection on cancer mortality and years of life lost (YLLs) in Brazil, Russia, India, China, South Africa, the United Kingdom (UK), and United States (US).

Methods: We collected population attributable fractions of the four risk factors from global population-based studies and applied these to estimates of cancer deaths in 2020 to obtain potentially preventable cancer deaths and their 95% confidence intervals (CIs). Using life tables, we calculated the number and age-standardised rates of YLLs (ASYR).

Koban culture genome-wide and archeological data open the bridge between Bronze and Iron Ages in the North Caucasus.

The North Caucasus played a key role during the ancient colonization of Eurasia and the formation of its cultural and genetic ancestry. Previous archeogenetic studies described a relative genetic and cultural continuity of ancient Caucasus societies, since the Eneolithic period. The Koban culture, which formed in the Late Bronze Age on the North Caucasian highlands, is considered as a cultural "bridge" between the ancient and modern autochthonous peoples of the Caucasus.

Completeness of regional cancer registry data in Northwest Russia 2008-2017.

Background: A national framework for population-based cancer registration was established in Russia in the late 1990s. Data comparability and validity analyses found substantial differences across ten population-based cancer registries (PBCRs)in Northwest Russia, and only four out of ten met international standards. This study aimed to assess the completeness of the PBCR data of those registries.

Mid-holocene Brown Bear (Ursus arctos) from the Bolshoy Lyakhovsky Island (New Siberian Islands).

A morphological description is provided for a unique find of a frozen mummified subfossil brown bear (Ursus arctos L., 1758), found for the first time ever. The find is a well-preserved bear carcass of approximately 3500 years in age.

Building a strong foundation: How pre-doctorate experience shapes doctoral student outcomes.

The effectiveness of doctoral programs has been a major topic of interest for national policies, universities, and researchers for decades now. However, studies that try to identify factors associated with doctoral students' success usually focus on characteristics measured during doctoral training, while the role of pre-doctorate characteristics remains underexplored. This research aims to fill this gap by examining whether and how various aspects of pre-doctorate experience-academic achievements, research experience related and unrelated to the dissertation topic, and teaching experience-contribute to the successful defense of the doctoral dissertation.

Sea of opportunities: marine genomics in an era of global environmental change.

Overexploitation of natural resources and pollution of seas, acidification of the ocean, and rising temperatures all contribute to the destruction of marine habitats and, in 2015, the protection of the ocean became one of the UN Sustainable Development Goals (SDG 14: Life Below Water). This collection aims to highlight the molecular genetic changes currently happening in marine organisms.

Whither repeat players? Litigation experience and success in court: Evidence from Russian commercial courts.

This paper tests the party capability theory of Galanter (1974) using the universe of legal entities and their 9.8 million commercial disputes in Russia in 2012-2019. We find that repetitiveness is negatively associated with litigation success in general.

Tales of resilience: voices from detention and imprisonment in Russia.

As the exposure to state violence could have long-term negative consequences on the survivors, we analyzed which optics and measures could be used regardless of the vulnerabilities of the individual, their social status and institutional context. We examine the ways in which law enforcement system challenges individuals and measures used to practice resilience.We use the concept of resilience within torturing environment to achieve our goal.

Gam-COVID-Vac, EpiVacCorona, and CoviVac effectiveness against lung injury during Delta and Omicron variant surges in St. Petersburg, Russia: a test-negative case-control study.

Background: Monitoring vaccine effectiveness (VE) remains a priority for epidemiological research throughout the COVID-19 pandemic. VE against infection declines with the emergence of new SARS-CoV-2 variants of concern (VOC), but VE against the severe disease remains high. Therefore, we aimed to estimate the effectiveness of COVID-19 vaccines used in Russia against lung injury during Delta and Omicron VOC surges.

COVID-19 vaccines effectiveness against symptomatic SARS-CoV-2 during Delta variant surge: a preliminary assessment from a case-control study in St. Petersburg, Russia.

Background: Studies of mRNA and vector-based vaccines used in different countries report acceptable levels of effectiveness against SARS-CoV-2 infection caused by the Delta variants of SARS-CoV-2. No studies estimated vaccine effectiveness (VE) of Gam-COVID-Vac and other vaccines used in Russia against symptomatic infection with Delta variant. In this population-based case-control study, we aimed to estimate the effectiveness of the Russian COVID-19 vaccines against symptomatic SARS-CoV-2 during the recent outbreak caused by the Delta VOC in October 2021 in St.

Vaccine effectiveness against referral to hospital after SARS-CoV-2 infection in St. Petersburg, Russia, during the Delta variant surge: a test-negative case-control study.

Background: The results of a randomised trial showed the safety and efficacy of Gam-COVID-Vac against COVID-19. However, compared to other vaccines used across the globe, the real-world data on the effectiveness of Gam-COVID-Vac, especially against the disease caused by the Delta variant of concern, was limited. We aimed to assess the effectiveness of vaccination mainly conducted with Gam-COVID-Vac in St.

Medical professionals' agency and pharmaceuticalization: Physician-industry relations in Russia.

In the contemporary world pharmaceuticals have become a go-to answer to a growing number of questions. This process of pharmaceuticalization gives rise to a concern with the increasing influence of the pharmaceutical industry on physicians' decision-making. Critics suggest that companies' for-profit-interests might compromise the integrity of medical practice.
